View Guard Clear Plastic Treatment is an industry first: a wet weather visibility enhancer specifically formulated for use on clear plastic enclosures such as Strataglass, EZ2CY and Eisenglass. Specially designed surfactants safely remove dirt and grit while advanced polymers repel rain, spray and salt to provide maximum visibility, even in heavy weather conditions. View Guard  also provides a barrier to damaging UV rays that can cause clear plastic to crack and turn yellow.
